3. Manufacturing Techniques for Eglin Structural Steel
Creating Eglin structural steel requires precise steps to ensure it meets strict standards. Below is the process from raw material to finished product.
Producción primaria
This step turns iron ore into steel:
- Creación de acero: Start with iron ore, carbón, and limestone.
- Alto horno: Melts iron ore to make pig iron (removes impurities).
- Horno de oxígeno básico (Bof): Blows oxygen through pig iron to lower carbon content (most common for Eglin steel).
- Horno de arco eléctrico (EAF): Uses electricity to melt scrap steel (for smaller batches or recycled Eglin steel).
Procesamiento secundario
Secondary steps shape the steel and enhance its properties:
- Laminación: Presses steel into sheets, verja, o vigas (hot rolling for large shapes, cold rolling for precision).
- Forja: Martillones o presiona el acero en formas complejas (P.EJ., piezas del motor) to improve strength.
- Fundición: Pours molten steel into molds (for large, custom parts like tank hulls).
- Tratamiento térmico:
- Recocido: Heats steel slowly and cools it to reduce hardness (más fácil de mecanizar).
- Apagado y templado: Heats steel to high temps, cools it quickly (temple) then reheats (templado) to balance strength and toughness.
Tratamiento superficial
Surface treatments protect Eglin steel from corrosion and wear:
- Cuadro: Applies protective paint (for indoor or mild outdoor use).
- Galvanizante: Caza de acero en zinc (resists saltwater and humidity—ideal for bridges).
- Revestimiento: Uses ceramic or polymer coatings (for high-temperature parts like engine blades).
- Voladura: Uses sand or grit to clean surfaces (prepares steel for painting/coating).
Control de calidad
Every batch of Eglin steel undergoes strict testing to meet standards:
- Inspección: Visual checks for cracks or defects.
